So the question is: Is there a PIC for my PICkit1 that has an eight bit wide output GPIO?
None that I can think of. The 14 pin PICs will have two ports with 6 each.

You migh get creative and shift the bits 4 four places.
Lower four to one port, upper four to the other???

Or...

I think Darrel had a way of re-mapping the pins/ports...
